United States Patent PIPE WRENCH STAND Joseph L. Dull, Seminole, Okla. (P.O. Box 65, Pampa, Tex.)

Filed June 5, 1959, Ser. No. 818,446

3 Claims. (Cl. 81-41) This invention relates to a novel pipe wrench stand for holding and supporting a pipe wrench while clamped on a pipe section relative to which another pipe section is to be rotated.

The primary object of the invention is to provide a simpler, more efiicient, and more easily used device of the kind indicated, which is desirably devoid of wrench clamping bolts, jaws, and the like, without sacrificing wrench-holding ability, and to which a pipe Wrench can be more quickly and easily applied and removed.

Another object of the invention is to provide a device of the character indicated above which is composed of a small number of simple and easily assembled parts, and which can be made in rugged and serviceable forms at relatively low cost.

Other important objects and advantageous features of the invention will be apparent fr om the following description and the accompanying drawings, wherein, for purposes of illustration only, a specific form of the invention is set forth in detail.

In the drawings:

Figure l is an exploded perspective view of a device of the invention;

Figure 2 is an enlarged end elevation, taken from the right of Figure 1; and

Figure 3 is a vertical longitudinal section taken on the line 33 of Figure 2, showing a pipe wrench secured in operative position on the device.

Referring in detail to the drawings, wherein like numerals designate like parts throughout the several views, the illustrated stand, generally designated 10, compirses a longitudinally and horizontally elongated, inverted U- shapcd form, longer than a pipe wrench W to be accommodated, and composed of a straight horizontal bar 12 at whose ends standards 14 of similar height depend, and have fixed on their lower ends at their midpoints cross bars 16, which serve as feet for supporting the device non-rockably upon a supporting surface S, such as a floor or the ground.

As shown in detail in Figure 3, the horizontal bar 12, the standards 14, and the cross bars 16 are suitably and preferably tubular elements, such as lengths of rigid pipe of the same diameter, which are fixed to each other by means of

weldings

18, 20, respectively.

Fixed to and upstanding on the upper side of the horizizontal bar 12, adjacent to a first end 24 thereof, is a perpendicular tubular standard 26, which can also be a length of pipe, and be secured in place by a welding 28. The inward side of the standard 26, facing the second end 30 of the horizontal bar 12 is formed with a vertically elongated, closed slot 32, which is spaced above the bar 12. The slot 32 is slightly wider and slightly taller than the fiat handle 34 of such as a conventional Stillson pipe wrench W. Removably engaged through

holes

36 and 38 provided in opposite sides of the standard 26, on a level with the rnidheight of the slot 32, is a diametrical retaining pin 40, having a head 42 on one end thereof.

At a point near to and spaced from the second end 30 of the horizontal bar 12 is an upstanding fixed bracket 44, which is preferably in the form of a fiat plate 46 having in its lower end a semi-circular notch 48, receiving the top side of the bar 12, with weldings 50 along the notch at opposite sides of the plate, securing the plate 46 to the bar 12 at an inwardly inclined angle, canted toward the standard 26.

The bracket plate 46 is taller than the standard 26 and has a preferably rounded upper end 52 which is on a level spaced above the standard 26. The bracket plate 46 is centrally formed with a closed vertical key-hole slot 54, having a relatively narrow, parallel-sided upper portion 56 to conformably receive a related part of the flat wrench handle 34, and a wider arcuate-sided lower portion 58 to accorndodate the wider frame portion 58 of the wrench, at the forward end of the handle 34, through which the shank 60 of the movable wrench jaw 62 works, and which carries the fixed jaw 64 of the wrench, and accommodates the usual clamping nut 66.

As apparent from Figure 3, the bracket 44 and the standard 26 are spaced from each other along the horizontal rod 12 at a distance less than the length of the wrench to be held, and such that with the wrench frame portion 48 engaged in the bracket key-hole slot 54, the terminal end portion 68 of the wrench handle 34 is engaged through the standard slot 32. The terminal end portion 68 has a usual hole or slot 70, and the retaining pin 40, being passed through the boss:

holes

36 and 38 and the wrench handle hole 70, the wrench W is securely held in position on the device 10, with its jaws extending upwardly, to receive a pipe section or the like to be clamped therebetween. The relatively close fitting engagements of the bracket and standard slots with the wrench serve to hold the wrench, non-rockably and nonrotatably in a vertical or perpendicular plane, with the wrench canted longitudinally toward the standard 26.

The cross bar feet 16 are of sufiicient lengths to reach beyond the opposite sides of the horizontal bar 12, so as to provide wide bearings upon a supporting surface, which give the device substantial resistance to being overturned to rocked upon a surface while the device is in use. When a wrench is secured in place on the device 10, the wrench serves as a convenient carrying handle for the device.

In use, a pipe section is clamped between the jaws of the Wrench W, so as to be supported in a stationary position, crosswise of the device 10, and held against rotation, while another pipe section is rotated to screw the same onto or off of the clamped pipe section, so that one man can perform the Work, without the assistance, otherwise necessary, of a second man to hold the stationary pipe section. The device 10 can also serve as a pipe vise, for such operations as pipe threading.

Although there has been shown and described herein a preferred form of the invention, it is to be understood that any change or changes in the structure of and in the relative arrangements of components are contemplated as being within the spirit and scope of the invention as defined by the claims appended hereto.

What is claimed is:

1. A pipe wrench stand comprising an elongated horizontal bar having first and second ends, a tubular standard fixed on and upstanding on said bar at said first end, said standard having a closed wrench handle receiving slot in the side thereof facing the second end of the bar, a removable retaining pin extended crosswise through said standard for retaining engagement with a wrench handle, and an upstanding bracket fixed on said bar at said second end having therein slot means for non-rotatably receiving the frame of a pipe wrench and an outer side to be abutted by a wrench frame.

2. A portable pipe wrench stand comprising an elongated horizontal bar having first and second ends, an upstanding tubular standard fixed on said bar at said first end, said standard having a closed slot facing said first end for receiving a wrench handle non-rotatably therethrough, a removable pin extending across the interior of the standard for holding a wrench handle extending through said slot, and an upstanding bracket fixed on said bar at said second end, said bracket having a closed slot, the bracket slot being narrower than a wrench head receiving a wrench head portion narrower than the head, and said bracket having an outer side 'engageable by a wrench head to limit shifting of the wrench toward the standard.

3. A portable pipe wrench stand comprising an clongated horizontal bar having first and second ends, an upstanding tubular standard fixed on said bar at said first end, said standard having a closed slot facing said first end for receiving a wrench handle non-rotatably therethrough, a removable pin extending across the interior of the standard for holding a Wrench handle extending References Cited in the file of this patent UNITED STATES PATENTS 243,277 Love June 21, 1881 444,779 Greenamyer Jan. 13, 1891 1,142,617 Patterson June 8, 1915 1,277,162 Wegner Aug. 27, 1918 1,336,755 Parmelee Apr. 13, 1920 1,941,889 Freeman Jan. 2, 1934 2,490,858 Deddo Dec. 13, 1949 2,553,283 Stratton May 15, 1951
